Henry S. Dziekan III/WireImage(LOS ANGELES) -- Chris Hemsworth may be best known for his hunky role as Thor in the Avengers family of movies, but in new film Rush, he’s showing his fans a new side – specifically his backside.

In the movie, Hemsworth, 30, shows off his naked butt twice, which he told People magazine was the hardest part of shooting.

“To take your clothes off in front of 100 people and cameras was something I wasn’t comfortable with,” he told People. ”To be honest, it was embarrassing.”

Most women might get a little uncomfortable about their husbands showing off their goods for the world to see, but Hemsworth said his wife Elsa Pataky didn’t mind.

“It was more uncomfortable for me to see than her,” he said. “I think she enjoyed it.”

Rush, directed by Ron Howard and also starring Olivia Wilde, tells the story about the rivalry between race car drivers James Hunt and Niki Lauda in the 1970′s.
